If you were to isolate a molecule containing uracil, all of the following are most likely true EXCEPT
A)it contains codons that represent amino acids.
B)it is single stranded.
C)it also contains guanine.
D)it contains deoxyribose sugar.

Question

Quizplus · Accepted Answer

Uracil is a nitrogenous base found in RNA, which contains ribose sugar instead of deoxyribose sugar found in DNA. Therefore, a molecule containing uracil cannot contain deoxyribose sugar, making option D false. Options A and B are true because uracil forms codons in mRNA that code for specific amino acids, and RNA is typically single-stranded. Option C is possible but not guaranteed because uracil can pair with adenine as well as guanine in RNA.
